Post-Storm Coastal Terrain Model for Northern Ireland

Northern Ireland's north coast soft sediment areas were surveyed with LiDAR in March 2022 following storms Dudley, Eunice, and Franklin. This dataset is a Digital Terrain Model (DTM) created from that survey, covering Curran Strand, Portrush East Strand, Portstewart Strand, and Downhill Beach to Magilligan. It is formatted to allow direct comparison with a baseline topographic LiDAR survey from 2021 to ascertain coastal change.

Use Cases

• Quantifying volumetric beach loss based on post-storm elevation data.
• Modeling coastal erosion rates by comparing this DTM to the 2021 baseline survey.
• Informing coastal management and defense strategies for soft sediment shorelines.
• Assessing specific storm impact (Dudley, Eunice, Franklin) on sandy beach morphology.

Strengths

• Provides a temporally specific snapshot captured in March 2022, following a known series of storm events.
• Designed for direct comparability with a 2021 baseline survey, enabling change detection.
• Cross-platform presence (eu_open_data, uk_data) signals official importance and reuse.

Limitations

• Column names and data structure are unknown, limiting immediate analytical use.
• Dataset size, row count, and spatial resolution are not provided.
• Metadata for some platform entries is incomplete (e.g., missing 'Last updated' dates).
